To all whom t may concern.'

Be it known that I, SAMUEL H. CONWELL, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Gondola-Car End Walls,of which the following is a specification.

My invention relates to the construction of railway cars, lmoreparticularly gondolak cars, and has for a primary object to provide areinforced sheet metal panel for the end wall of a railway car of thistype together with novel means for rigidifying the marginal portionsofthe panel and to provide means. for securely attaching the panel tothe sidewall structure and underframing of the car whereby the end wallof the car will be rigidified to, effectively resist the various thrustsand pressures to which car end structures are subjected.

A'further and more specific object of the I invention is to provide anovel top chord` construction for a sheet metal gondola car which willbe very strong and rigid vso as to be capable of withstanding the roughusage to which this part of the car is subjected, and which, moreover,will give reinforcement to the entire'superstructure ofthe car.

The invention consists in the new and limproved constructions,varrangementsl and such other incidental objectsas will appear,

from the following description of my invention.

My invention is illustrated in certain preferred embodiments in theaccompanying drawings, wherein ,Fig l is a vertical section through oneend of a railway car of the gondola type,

illustrating an end construction made in accordance with my invention.

AReferring irst` to Figs. 1 to 4 inclusive of the drzuvings-fl haveshown and will devscribe my invention in connection with a gondola carconstruction though ity willv be obvious that certain of the. featuresembodied in this invention might be readily used in connection with boXcars. I, therefore, do not wish, to limit the invention to thespeciicuse shown or to the structural feature described except in so faras specic -limitations may appear in the appended claims. l

The end structure shown in Figs. 1 to 4 inclusive consists preferably ofan end panel made up of two. sheets designated 10 and 1lrespectivelyformed with a plurality of horizontally disposedcorrugations 12-13 which extend uninterruptedly across the car from side`to side thereof and terminate with the usual ltapered terminals 14, -15within. the edges of the sheets. VThe sheets are arranged face'to faceand secured together by rows of rivets 16` on opposite sides of thecorrugations 12-13. The said 95 corrugations 12-13 .are preferablydisposed opposite one to another so' as to provide'hollow reinforcingbeams whichextend across the car end. The loweredges'of the sheets arebent in opposite directions to 100* provide flanges 17-13 adapted to besecured to the underfraining 19 of the car. The vertical edges of thesheets are bent rearwardly to provide angular attaching flanges 20-21which overlap the outer and inner surfaces of the side walls 22 and aresecured to said side walls by means of bolts 23. The upper edges of thesheet lO-ll are bent in opposite directions to provide a rigidifyingchord for the upper margin of the end panel. This rigidifying chordconsists preferablyv of webs 24-25 having depending reinforcing flanges26-27 respectively. The top chord construction is firmly attached to theside wall st-ructure of the car by means of anglar stiffening members orgussets 23"'riveted to the web 24 and web 25 of the vchord member byrivets 29-'30 respectively, overlapping the louter surface of thesidewalls vand secured thereto by means of bolts 31 passing through theside wall boards 22 and bolts 32 passingthrough the side wall boards andfalso through the vertical 'attaching flanges 20-21 of the sheets -lO-llrespectively.

In the modification illustrated Fig. 5 the end panel consists ofcorrugated sheets 33 34 formed along 'their vertical edges with angularattaching flanges 35-36 respectively which overlap the side walls 37 ofthe car. The' upper edge of the panel is rigidified by means of a topchord Iformed by turning the upper edge of the sheet 33 outwardly toprovide a flange 38 and bending the upper edge of the sheet 34 inwardlyto provide an oppositely disposed flange When forming a metal sheet withrigidifying corrugations the edges of 'the sheetvv are distorted ordrawn inwardly by the pressing operation. This fact is taken advantageof in the chord construction illustrated in Fig. 5 in that the upperedge of the sheet 34 is bent over without removing the irregular portionof the edge.

i :Bv forming the flange 39 in this manner the kflange is increased inwidth toward the sides of the car. The extremities of the flange 39 arepreferably bent downwardly as indicated at 40 and are suitably securedto the vertical flanges 3G by bolts 4l passing through the side walls 37of the car.

The modification illustrated in Fig. 6

shows an end panel in which the car struc# ture is rigidified adjacentthe corner Iposts 42.0f the car. The vertical edges of the inner sheetof this structure are preferably' bent as indicated at 43-44 so as tofit around the inner faces of the corner posts 42, the outer edge beingbent rearwardly las indicated Vat 45 and secured to the side ,wall 46 ofthe car. The outer sheet designatedr47 in this figure may be constructedvsubstantially the same as the outer sheet in ilo-4 inclusive and the'end `'panel may be secured to the side wall construction of the car bymeans of the gussets 23 in substantially the same manner as thatillustrated in Figs. l to 4 inclusive.

In Fig. 7, I have illustrated another modied form of end construction inwhich the top chord of the panel is provided by bending the upper edgesof the sheets 48 49 in opposite directions as indicated at :iO-51. Achannel beam 52 is fitted over the flanges -51 and secured thereto byrivets 53.

In Fig. 8, I have shown a modification in which the end panel iscomposed of two sheets 54, 55, one fiat and the other corrugated, havingoppositely turned flanges 5G, 5T forming the top chord of the end. Thesheets are preferably secured together hy rivets on opposite sides ofthe corrugations 59 of the sheet 55. In Fig. 9 the arrangement issimilar except that the top chord formingranges are turned both in thesame direction. Sheet 60, the vouter sheet preferably is formed withcorrugations and with an out turned flange 6l having a depending rim 62.The inner sheet 63 may be flat and is formed with an out turned vflange64 secured to flange 6l by rivets 65.
